For bugs in the Composer application, the high-level application that is used to create HTML documents. Appropriate bugs include those not belonging to the core editor engine, including an inability to launch the composer application and problems in the general user interface of the composer application or toolbar, such as incorrectly behaving toolbar buttons and menu items, and incorrect dialog behavior. Please see the bug description for Editor: Core for more information.

The entire page is contained in a <PRE> tag, which means preformatted text.
See the definition of <PRE> at
http://www.w3.org/TR/REC-html40/struct/text.html#h-9.3.4 which says:
...
The PRE element tells visual user agents that the enclosed text is
"preformatted". When handling preformatted text, visual user agents:
* May leave white space intact.
* May render text with a fixed-pitch font.
* May disable automatic word wrap.
...
The <PRE> tag contains an invalid WRAP="" attribute
The page is not valid HTML. Please check the code at http://validator.w3.org/
Marking invalid, though it is interesting that Mozilla browser DOES wrap the text

Perhaps I was not clear before.
1) The sample page was generated EXCLUSIVELY by composer.
2) There was NO manual html editing on the page after it was generated.
3) I did not in any way (that I know of) ask for the page to have this "pre
wrap" feature.
4) Since the page does not display properly in IE6, my conclusion is that
Composer is adding this "illegal" code in error.

While this might or might not be a bug (seems like it is), this is the same as
bug 210052 (which Joe already reported some time before this one).
